The offer allows customers to double up the data on Verizon’s tiered data plans for the same price that they would normally cost.

Broken down, that looks like this:

Normal Offer: 2GB/mo for $30 After Promo: 4GB/mo for $30

Normal Offer: 5GB/mo for $50 After Promo: 10GB/mo for $50

Normal Offer: 10GB/mo for $80 After Promo: 20GB/mo for $80

Unfortunately, that extra data won’t be attainable after the 5th. However, all hope is not lost. Verizon has killed and brought back the promo offer before.

In fact, this will be the second time that Verizon has ended its double data promotion. The first promotion lasted from November until January. The carrier then brought back the offer in February and it has since been available to customers that are signing up for a new contract or renewing a current one.

However, this could not come at a worse time for potential Galaxy S III owners who want to get the phone when it launches in June.

It appears that this offer won’t be around for that launch as carriers in the United States have yet to make their plans known and the phone is slated to launch in Canada on June 20th, a date that might be the day it arrives in the U.S. as well.
